Özet
In this study, post-mortem myofibril proteins change in myosin heavy chain (MHC) mass using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), texture properties such as hardness, stickiness, cohesiveness, elasticity, chewiness, gumminess and stress relaxation test parameters (Fmax, Fmin and Fmax-Fmin) were determined and compared on the days 0, 3, 6 and 9 in three different trout species (Oncorhynchus mykiss, Salmo trutta fario and Salvelinus fontinalis). In terms of texture properties, post-mortem hardness, cohesiveness, elasticity, chewiness and gumminess were decreased day by day, whereas stickiness, Fmax, Fmin and Fmax-Fmin were significantly increased (p <.05). According to SDS-PAGE results, a decreased value on MHC was determined (p <.05). Texture properties and SDS-PAGE results were found different among groups (p <.05). Correlation between chewiness, gumminess, MHC and hardness; between chewiness and gumminess; between Fmin, Fmax-Fmin and Fmax; between Fmin and Fmax-Fmin were significant. As a result of the study, S. fontinalis exhibited least deterioration in comparison with other species and it was determined that SDS-PAGE results and texture properties support each other.
